2. The device of claim 1 , comprising the at least one processor.

3. The device of claim 1 , wherein the UI presents an alpha-numeric indication of a speed of a vehicle other than the vehicle in which the UI is presented.

4. The device of claim 1 , wherein the UI includes an alpha-numeric indication of a type of a vehicle reporting via the wireless network.

5. The device of claim 1 , wherein the UI presents icons unique to vehicle types based on type information reported by the vehicles through the wireless network.

6. The device of claim 1 , wherein the UI presents an alpha numeric indication of a vehicle having a speed satisfying a threshold.

7. Device, comprising: at least one computer readable storage medium bearing instructions executable by a processor; and at least one processor configured for accessing the computer readable storage medium to execute the instructions to configure the processor to: present on a display a user interlace (UI) including one or more filter selectors selectable to filter traffic/road reports uploaded from vehicle ad hoc networks (VANETs) and presented on the UI, the one or more filter selectors including two or more of: a “local” selector which when selected causes information to be presented on the display showing information only within a predetermined distance of the display, a “state” selector which when selected causes information to be presented on the display showing information only for an entire state in which the display is located, and a “national” selector which when selected causes information to be presented on the display showing information only for an entire nation in which the display is located.

8. The device of claim 7 , wherein the UI indicates a location of the device on which the UI is presented, along with locations of plural vehicles in a wireless mesh network that includes a vehicle in which the UI is presented, the locations of the other vehicles being received through the mesh network.

9. The device of claim 7 , wherein the UI presents arrows whose magnitudes and directions are defined by headings and speeds of respective vehicles as reported is the VANET.

10. The device of claim 7 , wherein the UI presents an alpha-numeric indication of a speed of a vehicle other than the vehicle in which the UI is presented.

11. The device of claim 7 , wherein the UI includes an alpha-numeric indication of a type of a vehicle reporting via the VANET.

12. The device of claim 7 , wherein the UI presents icons unique to vehicle types based on type information reported by the vehicles through the VANET.

13. The device of claim 7 , wherein the UI presents an alpha numeric indication of a vehicle having a speed satisfying a threshold.

14. The device of claim 7 , wherein the filter selectors include all of a “local” selector which when selected causes information to be presented on the display showing information only within a predetermined distance of the display, a “state” selector which when selected causes information to be presented on the display showing information only for an entire state in which the display is located, and a “national” selector which when selected causes information to be presented on the display showing information only for an entire nation in which the display is located.

15. The device of claim 7 , wherein the UI presents indications based on information reported by a VANET indicating current road condition.

16. The device of claim 7 , the one or more filter selectors including a “local” selector which when selected causes information to be presented on the display showing information only within a predetermined distance of the display.

17. The device of claim 7 , the one or more filter selectors including a “state” selector which when selected causes information to be presented on the display showing information only for an entire state in which the display is located.

18. The device of claim 7 , the one or more filter selectors including a “national” selector which when selected causes information to be presented on the display showing information only for an entire nation in which the display is located.
